Gas Odorant

DMS odorant useDimethyl Sulfide (DMS) has an odor that is detectable at very low levels. For this reason, it is included as a component of dangerous gases to allow the detection of leaks by smell.

DMS has an advantage over odorants like methyl mercaptan in that it is very chemically stable. Mercaptan odorants oxidize over time, and the ability to smell their presence diminishes.
